Siri is insanely loud with Jabra Journey

I've seen a number of threads regarding Siri volume being too low with bluetooth devices - but none that say it's too loud.

Even if I try and adjust the volumn on my bluetooth hands free speaker - Siri still seems to kick in at maximum volume.

I just downloaded the software update for the Jabra Journey and it didn't help. Has anyone else had similar problems? - I've looked and can't find a way to control the volume of Siri on the phone anywhere either.

Thanks
